The present invention relates to shade rollers in general, but more particularly to rollers of the type having an outer metallic sheath.

An object of the invention is to provide means whereby a curtain shade may be quickly and easily attached to its roller and whereby the attached curtain shade is firmly held on its roller against force applied to the shade during its use.

Another object of the invention is to provide improved means, whereby a shade roller may be so constructed as to enable its length to be readily adjusted to suit the requirements of any particular conditions, and yet may be manufactured at little additional cost.

A further obj ect of the invention is to provide a shade roller construction enabling the length of the roller to be readily adjusted and also enable quick and easy attachment oftheshade to the roller. y

` These and further objects will more fully appear in the following description taken in connection with the accompanying drawings,

in which Fig. 1 is a view in elevation of anV adjustable shade roller; Fig.,2 is an enlarged fragmental view in elevation of the shade roller rotated approximately 180O away from its position shown in Fig. 1, and having thereon a shade fabric and a plurality of fasteners w securing the fabric to the roller; Fig. 3 is a perspective view of an improved shade fastener; Fig. 4 is an enlarged fragmental longitudinal sectional view of the shade roller taken on the plane indicated by the line 4-4 of Fig. 1, showing improved means for adjusting the length of they rollers; Fig. 5 is a cross-sectional view of the roller as taken on the plane indicated by the line 5 5 of Fig. 4; Fig. 6 is a fragmental longitudinal sectional view of a shade roller showing a possible construction thereof; Fig. 7 is a view of the top edge portion of the shade fabric having openings formed therethrough; Fig. 8 is an enlarged cross-sectional' view on the plane indicated by the line 8-48 of Fig. 2; and Fig. 9 is a similar view on the plane indicated by the line 9--9 of Fig. 2.

In carrying out the invention, the fasteners 110 (Fig. 3) are formed of spring metal strips,

and are rolled or coiled to such a diameter that they retain a set of curvature .the circumference of the roller. i Alined longitudinal shoulders 15 and 15 (Fig. 2), formed respectively on the longitudinally movable parts 17 and 17 (Fig. 1) ofthe eX- tensible roller 11 cooperate with longitudinal edges 2O of the fasteners 10 to assure alinement of the fasteners and prevent their displacement on the roller. The shade material is creased between said shoulders and said edges of the fasteners. Preferably, the fasteners are formed at their clamping edges with projections or tongues 21, which extend through openings 22, predeterminedly formed through the fabric 14 at a distance from its upper end or edge, and snugly engage into recesses 24,V (see Figs. 2, 6 and 9) formed in longitudinal alinement on the roller 11. A simple method of forming the shoulders 15 and 15 and the recesses 24 will become apparent in the following description.v

In the embodiment of the invention shown in the drawings, the roller 11 is of the type generally referred to in the trade as tin rollers. The metal sheath of this roller 11 is preferably made in accordance with the process disclosed'an'd claimed in my aforementioned patent. Referring particularly to Figs. V1, 6 and 8, part 17 ofthe extensible roller 11 consists of a sheet metal strip or strips 25, rolled or curledinto circular form, during the process of manufacture, to a diameter smaller than the required diameter of the finished roller, and of a plurality of wooden cylindrical cores or blocks 26, positioned at intervals along the length of the roller within'the curved strip or strips 25. The longitudinal margins or edge portions 27 and 29 of the metallic strip or strips 25, when the latter are assembled on the blocks 26, overlap one another, and'require no seaming or soldering, the tension created in the curved strip or strips 25 upon insertion of the blocks 26 therein maintaining the circular form of the roller throughout its length. Pins or nails 30 may be used to secure the tubular strip or strips to the enclosed blocks 26. If the roller is to be made of a plurality of sections, each consisting of a curved strip 25, the sections may be joined together by means of blocks 31 extending partly within each of the .adjacent section ends, and may be secured to them as before described. In this assembly of the sections, they are caused to be so positioned that the longitudinal shoulders 15 formed by the outer overlapping margins 29 of the strips, are broughtin alinement with one another, one continuous shoulder being thus formed longitudinally of the roller part 17. lVithin the roller part 17 is fitted the usual shade rewinding spring and locking devices, (not shown in the drawings), the usual winding key 32 projecting from the outer end of said roller part for proper support in a slotted bracket.

Referring to Figs. 1, 4 and 5, part 17 of the roller 11 consists of a separate metallic end section 25', of suitable length and formed `in the manner hereinbefore described. Lengthwise adjustment of the roller 11 is provided by a circular wooden core or rod 34, also of suitable length, projecting from the section or innermost section 25, and sliding by eX- tending within the end section 25', a telescoping fit being maintained by the contractile tension of the surrounding sheath 25'; the rod 34 is fixedly secured to the section or innermost section 25 in a mannerv which will be later described. rl`he outer end of the sheath 25 encloses a wooden plug (not shown in the drawings), secured to the sheath 25' as by nails or pins 30', vhich plug car 1ies the usual journal pin The overlapping margins 27 and 29 of the sheath 25 require no seaming, the contractile tension being amply sufricient to insurea sufficiently tight grip of said sheath around the rod 34 to give the roller rigidity throughout its length.

In accordance with the invention, respective margins or overlapping free edges of the` metallic sections of the roller, are stamped or struck up, during the process of manufacture, at predetermined portions of the rollers length to form protuberances 3o; (see Figs. 2 and G). The latter cooperate with the other overlapping margins, in this case the inner margins 27 and 27', forming shallow pockets or recesses 24, into which the proj ections or tongues 21 of the fasteners 10 engage, when positioning the latter on the shade and roller. It is to be noted that the process of making the roller 11, as described, is advantageous in that it affords easy and inexpensive means of forming the shoulders 15 and 15', particularly by reason of the fact that themetallic sheaths require no seaming nor soldering, and also forming the recesses 24 and locating all of the latter in longitudinal alinement with one another.

rlhe openings 22, preferably oblong in shape in the direction of the width of the shade fabric, are formed through said fabric at such a distance from its upper end or edge and at such intervals along its width, that, when the shade is properly positioned on the roller, the struck up portions or protuberances 36 lie within said openings 22. thereby rendering the recesses 24 accessible for posi- `ioning therein of the tongues 21 of the fasteneis 10, and a sufficient length of fabric is provided to be wrapped around the roller beneath the fasteners 10 as shown in Figures 8 and 9. These openings 22 are preferably punched out by means of an instrument. which is positioned along the upper end or edge ofthe shade fabric 14, whereby proper alinement of the openings 22 and their proper spacing from said upper edge are afforded, obviating the necessity of drawing a line on the fabric prior to forming of the openings.

An important feature of the present invention resides in the cooperative action of the side edges 20 of the fasteners 10 with the aforesaid longitudinal shoulders 15 and 15 formed by the outer overlapping margins of the metallic sheaths 25 and 25'.

As clearly shown in Figures 8 and 9, the edge portion 12 of the shade fabric 14 is wrapped around the roller in such a direction away from a shoulder 15 or 15 that, when the fasteners 10 are initially positioned over a substantial part of the edge portion 12, they may slide arcuately over said portion 12 toward said shoulder for proper positioning of their tongues 21 within corresponding recesses 24. The shoulder limits this sliding movement of the fasteners 10, and substantial pressure is then applied to the fasteners to insure a firm clamping action of the shoulder and fastener edges 20 on the fabric 12, crimped portions or creases 87 being thus formed inthe fabric at the edges of the areas of those portions which are gripped between said shoulder and fastener edges. Thus, when force or tension is applied to the shade 14 during its use, the fasteners 10 are effectively prevented from becoming displaced from their positions, firmly securing the shade on the roller, by the cooperative action of the fastener edges 2O on the shoulder 15 or 15', andthe additional friction created by the crimped portions 37 of the fabric materially assists the function of the contractile fasteners 10 in retaining the edge portion 12 of the shade against displacement from its secured position on the roller.

In Vaccordance with the invention, the rod is formed with a longitudinal slot 39, which may conveniently extend throughout its length, and the outer sheath 25' and the sheath 25 adjacent thereto are stamped or manufacture, to form inwardly directed projections or depressions 40 and 41 (see Fig. 4l),

which extend within the aforesaid slot 39.1

The depression 10, formed on the section 25, is iixedly secured within the slot 39 by a nail or pin L12, and, if desired, additional means 30 may be used to fiXedly secure said section 25 on the rod 34. The depression 41, formed on the section 25, is adapted to slide within the slot 39 longitudinally thereof when adjusting the length of the roller.

From the above description, it becomes apparent that, by reason of the corresponding or duplicate positions of the depressions 10 and 41 on the end edges of the adjacent sections 25 and 25, simple and economical means are provided for alining the shoulder 15, formed by the outer overlapping margin or margins 29 of the section or sections 25, with the shoulder 15, formed by the cuter overlapping margin of the end section 25. In assembling the parts, one end of the rod 3a, having the slot 39 thereon, is partly inserted in the section or outermost section 25, with the depression a() sliding in the slot 39, and said depression Ll0 is fixedly secured within the slot 39. The other end of the rod 34 is inserted in the section 25, with the other depression 41 sliding in the slot 39, the shoulder 15 immediately alining itself by necessity with the shoulder 15, with no further pro oedure involved. Rotational movement of the sections 25 and 25 during assembly of the parts is prevented, and arcuate displacement of the shoulder 15 relative to the shoulder 15, when adjusting the rollers length, is also prevented.

If part 17 of the eXtensible roller 11 is to consist of a plurality of sections 25, the cores or blocks 31, joining these together, may, if desired, likewise be formed with longitudinal grooves, and adjacent ends of the sections 25 likewise formed with corresponding depressions engaging into said grooves, as a means to facilitate alinement of theV shoulders 15 in assembling said sections 25 on said blocks 31.

Evidently, by reason of the permanent alinement of the shoulders 15 and 15", the clamping of the shade, by the means hereinbefore described, on both parts 17 and 17 of the eXtensible roller 11. is greatly facilitated. If desired, a fastener or fasteners, having no tongue 21 formed thereon, may be used to clamp the fabric to the endsection 25', the cooperative action of the side edge 20 of a fastener with the shoulder 15 being alone sufficient to maintain the edge portion 12 of the fabric in permanent position on said end section 25.

The fasteners 10 and shoulder 15 or 15, co-

l, operating therewith, provide a quick and eflicient means of firmly holding the shade fabric in place, and, since they extend around the greater portion of the circumference of the roller, and since succeeding convolutions of the shade are wrapped over them, any displacement froin their normal positions is effectively prevented. If the fasteners are provided with tongues 21, the latter also serve to prevent displacement of the fasteners from their clamping position on the roller.
